Aliases: Jennifer Walters

Taken from Wikipedia:
She-Hulk (Jennifer Susan Walters) is a Marvel Comics superheroine. Created by writer Stan Lee and artist John Buscema, she first appeared in Savage She-Hulk #1 (February 1980).

She-Hulk has been a member of the Avengers, the Fantastic Four, Heroes For Hire, Defenders, Fantastic Force, and S.H.I.E.L.D. A highly skilled lawyer, she has served as legal counsel to various superheroes on numerous occasions. Her cousin is Bruce Banner, better known as The Incredible Hulk.

She-Hulk is immediately recognizable due to her size, green skin, and long green hair.

She-Hulk is a formidable hand-to-hand combatant, having been trained by Captain America and Gamora. Even in her Jennifer Walters form, she possesses sufficient skill in the martial arts to dispatch several would-be muggers much larger than she is.
